The ADA Bottom Plus 25 Sticks is a substrate fertilizer designed to restore nutrients in planted aquarium soil over time. It is enhanced with nitrogen and iron, two nutrients that can become depleted in the substrate as aquatic plants absorb them through their roots. This makes it especially useful for established planted aquariums where root-feeding plants need renewed nutrition.
The ADA Bottom Plus 25 Sticks is made primarily from natural soil similar to ADA Aqua Soil and breaks down gradually inside the substrate. It promotes healthier leaf colour and supports plants that actively absorb nutrients through their roots, such as Cryptocoryne, Echinodorus, stem plants and heavy-rooting foreground plants. The stick format makes it easy to place nutrients exactly where plants need them.
This product is ideal for refreshing older substrate, supporting root-heavy plants and improving growth in established aquascapes. Insert the sticks deep into the substrate using tweezers or a planting tool. Use approximately 1 stick per 15 × 15cm substrate area and avoid exposing the sticks above the soil surface.
